ALARM.

Application filed June 5, 1926. Serial Io. 113,993.

This invention relates to an alarm, the general objectof the invention being to pro vide means for exploding cartridges or the like when a door or other barrier-is tam-- pered with or a part, which is attached to the device to actuate the same, is moved by a person, animal or bird.

Another object of the invention is to so arrange the parts that the cartridges will he exploded in succession, with means for using cartridges oil dirderent calibre in the device."

A further object of the invention is to provide safety means for preventing operation ot the trigger means until the triggerectuated lever is moved.

This invention also consists incertein other teatures'ot construction and in the combination and arrangement of the several parts, to he hereinafter fully described, illustrated in the nccompenying drawings and specifically'pointed out inthe appended claims.

ln descriloing invention in deteil, reference will be had to the accompanying drawings wherein like charecters denote like or comesponding parts throughout the severed views, and in which Figure l. is e topplsn view ot' the device.

Figure 2 is en elevotion thereof.

l igure 3 is a bottom planview.

l igure d is a section on line of Figure 1. v v

lFie'ure is 's section on line 5-5 of Figure V p in these-views, 1 indicetes e supporting hoard or plate which is provided with the" legs 2 so thet it can be connected with or door trttme or other support. A peir o't lOI'ELGliGlJS 3 is mounted on the upper lece oi the plots and eech hrechet carries o shalt 4t to which n hammerii is coiniected .rcoiled spring 6 encircles each shaft and hes one end connected with the hammer. end the other end engages epart of the lorecket.

This spring tends to throw.- the herniner against as spring. pressed firing pin arr-- reng'ed adjecent' one ed e of the support. These pins pass through holes. formed in a top plots 8 fastened to the plate. ll hy the bolts. 9 and in the plate 1. The holes in the late 1, communicate withcartridge holding" holes 10 formed in a bottom plate 11 which is held against the underside of the plate 1" lay a bolt-12 provided with a wing nut 13.

, The holes 10 are (if diflerent sizesso as to hold cartridges A of differentcalibrfAfier the cartridges have been fired by the hamrner s rikin gthe pins 7,the nut 13 is removed trointhe bolt 12 so that the plste ll can he removed and the firing cartridges pushed from the holes 19 and new cartridges put in their place. Then the plate 11 is put back and held in position by the bolt 12 and the nut 13. A trigger it is provided for each hnier, esch trigger passing, througho holedo formed in the hose It and pivctelly supported therein by e pin 16. An, angle-shaped safety lever 17 is pivoted to the under side or the memher liter esch trigger, one. end of eechlever engeging the trigger and holding it in engagement with the hammer to hold the hammer retracted, it screw or pin 18 is carriedby the other end of each lever l7 and passes through on arc-shaped slot 19 in the hose 1..

A doulole lever 20 is pivoted intermediate its ends to the under side of the member l', as shown at 21, end esch end of sold lever has an extension 22 hinged thereto. Either one'of these extensions is adopted to. he engsged by a door or other harrier, portion of which is shown at B, hurt by turning; this extension on its hinge, the device will he rendered inoperative, es the lever will not he engeged hy the losrrier when the herrier is opened, 'llhe'lever 20 has n pair oil clips E23 ettached thereto, each of which is provided with a projection 24%, one oi which will engage one of the safety levers ill on the in itial movement or the lever 20 to move seid lever out out the path of the trigger, while the other projection will move it slide 25 till which will engage the other sei'ety lever to l move it out oil the peth of the other trigger. Then a bent turns 26 on thelever 20 will strike one oi the triggers and more it to releasing position so that its heer can he I thrown against the firing ,pin to explode the first cartridge and then s pert out the lever too 20 will strike the other trigger end move it to releasing, position to permitthe other hammer to fire the second certridge.

From the roregoing, it will he seen that l have provided snmple means" torerploding two cartridges, one after the other, so that the device can he usedto frighten away"- thieves attempting to enter e building or the like or'to frighten away animals, birds and the like which are'attempti to enter hen-- houses, coops or the like. stead of having the lever 20 actuated directly by the may be actuated from a distance by attaching a rope 27 or cable to the lever and to the barrier or the like. By making the lever double, as in Figures 1 and '3, either end can be used for actuation by aibarrier, After the device has been actuated, the

hammers are cocked by hand, the ,triggers and safety levers being moved to hold them cocked and thennew cartridges are put in.

It is thought from the foregoing descrip tion that the advantages and" novel'features of my invention-will be readily apparent.

I desire, it to 'be understood that-I may make changes in the constructionand in the "ment, a lever adapted to be actuated by a combination and arrangement oftheseveral parts, provided that such changes fall within thelscope of the appended claims. .?'.What I claim is 1 An alarm device of the class described comprising a supporting member, spring actuated hammers carried thereby, car
